The labels in the figures are: 1. an upper inlet port; 2. a lower air inlet; 3. an overflow port; 4. a stirring shaft; 5. feeding a coil pipe; 6. a coil pipe is arranged; 7. a lower opening is formed; 8. and the upper part is provided with a hole.

Detailed Description

The following detailed description is provided to further explain the technical features and advantages of the present invention by referring to the accompanying drawings in combination with the embodiments.

As shown in fig. 1-2, the utility model discloses a protective gas lets in tubular construction of reation kettle, including last inlet 1 and lower air inlet 2, last inlet intercommunication be located the internal hanging wall 5 of reation kettle jar, a plurality of trompils 7 down have been seted up to the hanging wall, the lower air inlet intercommunication is located the lower coil 6 of the reation kettle jar in, lower coil processing has a plurality of trompils 8 of going up, the external processing of reation kettle jar has overflow mouth 3, highly being less than the last coil of overflow mouth, the bottom surface of (mixing) shaft 4 is higher than the lower coil in the reation kettle.

Further, the upper coil pipe and the lower coil pipe are both in a disc pipe shape, as shown in fig. 2, the upper coil pipe is 20cm away from the upper edge of the overflow port of the reaction kettle, and the lower coil pipe is welded at the bottom of the reaction kettle. The equal partition processing of last coil pipe and lower coil pipe have 4 apertures, be 90 contained angles between each hole site, lower trompil and last trompil dislocation set, the aperture mean value of lower trompil is 8mm, the aperture mean value of last trompil is 12 mm.
